How to use UIMotionEffect in SwiftUI? - swiftui

Any idea how to use UIMotionEffect in SwiftUI? I was thinking there might be a way to connect the motion effect to a state variable and then using that variable in SwiftUI we get a similar result to UIKit.
Simple UIKit example
let value = 12
let verticalMotionEffect = UIInterpolatingMotionEffect(keyPath: "layer.transform.translation.y", type: .tiltAlongVerticalAxis)
verticalMotionEffect.minimumRelativeValue = value
verticalMotionEffect.maximumRelativeValue = -value
let horizontalMotionEffect = UIInterpolatingMotionEffect(keyPath: "layer.transform.translation.x", type: .tiltAlongHorizontalAxis)
horizontalMotionEffect.minimumRelativeValue = value
horizontalMotionEffect.maximumRelativeValue = -value
let group = UIMotionEffectGroup()
group.motionEffects = [horizontalMotionEffect, verticalMotionEffect]
view.addMotionEffect(group)

Using axis ranges to place labels at arbitrary category

As you can see in the below image. I want to add custom label ranges for y axis.
I have followed this tutorial and tried below code but it was not working, Any idea how to use categoryAxis with custom labels?
let range0 = categoryAxis.axisRanges.create();
range0.value = "MCR.INV-1";
range0.text = "MCR.INV-1";
let range500 = categoryAxis.axisRanges.create();
range500.value = "MCR.INV-2";
range500.text = "MCR.INV-2";
let range1000 = categoryAxis.axisRanges.create();
range1000.value = "PEV1.INV-1";
range1000.text = "PEV1.INV-1";
CategoryAxis ranges use category/endCategory for placement. Replacing value with category in your ranges will fix the problem.

M & Power Query: How to use the $Skip ODATA expression within a loop?

Good afternoon all,
I'm trying to call all of the results within an API that has:
6640 total records
100 records per page
67 pages of results (total records / records per page)
This is an ever growing list so I've used variables to create the above values.
I can obviously use the $Skip ODATA expression to get any one of the 67 pages by adding the expression to the end of the URL like so (which would skip the first 100, therefore returning the 2nd page:
https://psa.pulseway.com/api/servicedesk/tickets/?$Skip=100
What I'm trying to do though is to create a custom function that will loop through each of the 67 calls, changing the $Skip value by an increment of 100 each time.
I thought I'd accomplished the goal with the below code:
let
Token = "Token",
BaseURL = "https://psa.pulseway.com/api/",
Path = "servicedesk/tickets/",
RecordsPerPage = 100,
CountTickets = Json.Document(Web.Contents(BaseURL,[Headers = [Authorization="Bearer " & Token],RelativePath = Path & "count"])),
TotalRecords = CountTickets[TotalRecords],
GetJson = (Url) =>
let Options = [Headers=[ #"Authorization" = "Bearer " & Token ]],
RawData = Web.Contents(Url, Options),
Json = Json.Document(RawData)
in Json,
GetPage = (Index) =>
let Skip = "$Skip=" & Text.From(Index * RecordsPerPage),
URL = BaseURL & Path & "?" & Skip,
Json = GetJson(URL)
in Json,
TotalPages = Number.RoundUp(TotalRecords / RecordsPerPage),
PageIndicies = {0.. TotalPages - 1},
Pages = List.Transform(PageIndicies, each GetPage(_))
in
Pages
I got all happy when it successfully made the 67 API calls and combined the results into a list for me to load in to a Power Query table, however what I'm actually seeing is the first 100 records repeated 67 times.
That tells me that my GetPage custom function which handles the $Skip value isn't changing and is stuck on the first one. To make sure the Skip index was generating them properly I duplicated the query and changed the code to load in the $Skip values and see what they are, expecting them all to be $Skip=0, what I see though is the correct $Skip values as below:
Image showing correct Skip values
It seems everything is working as it should be, only I'm only getting the first page 67 times.
I've made a couple of posts on other community site around this issue before but I realise the problem I was (poorly) describing was far too broad to get any meaningful assistance. I think now I've gotten to the point where I understand what my own code is doing and have really zoomed in to the problem - I just don't know how to fix it when I'm at the final hurdle...
Any help/advice would be massively appreciated. Thank you.
Edit: Updated following #RicardoDiaz answer.
let
// Define base parameters
Filter = "",
Path = "servicedesk/tickets/",
URL = "https://psa.pulseway.com/api/",
Token = "Token",
Limit = "100",
// Build the table based on record start and any filters
GetEntityRaw = (Filter as any, RecordStart as text, Path as text) =>
let
Options = [Headers=[ #"Authorization" = "Bearer " & Token ]],
URLbase = URL & Path & "?bearer=" & Token & "&start=" & RecordStart & "&limit=" & Text.From(Limit),
URLentity = if Filter <> null then URLbase & Filter else URLbase,
Source = Json.Document(Web.Contents(URLentity, Options)),
Result = Source[Result],
toTable = Table.FromList(Result, Splitter.SplitByNothing(), null, null, ExtraValues.Error)
in
toTable,
// Recursively call the build table function
GetEntity = (optional RecordStart as text) as table =>
let
result = GetEntityRaw(Filter, RecordStart, Path),
nextStart = Text.From(Number.From(RecordStart) + Limit),
nextTable = Table.Combine({result, #GetEntity(nextStart)}),
check = try nextTable otherwise result
in
check,
resultTable = GetEntity("0")
in
resultTable
As I couldn't test your code, it's kind of hard to provide you a concrete answer.
Said that, please review the generic code I use to connect to an api and see if you can find where yours is not working
EDIT: Changed api_record_limit type to number (removed the quotation marks)
let
// Define base parameters
api_url_filter = "",
api_entity = "servicedesk/tickets/",
api_url = "https://psa.pulseway.com/api/",
api_token = "Token",
api_record_limit = 500,
// Build the table based on record start and any filters
fx_api_get_entity_raw = (api_url_filter as any, api_record_start as text, api_entity as text) =>
let
api_url_base = api_url & api_entity & "?api_token=" & api_token & "&start=" & api_record_start & "&limit=" & Text.From(api_record_limit),
api_url_entity = if api_url_filter <> null then api_url_base & api_url_filter else api_url_base,
Source = Json.Document(Web.Contents(api_url_entity)),
data = Source[data],
toTable = Table.FromList(data, Splitter.SplitByNothing(), null, null, ExtraValues.Error)
in
toTable,
// Recursively call the build table function
fxGetEntity = (optional api_record_start as text) as table =>
let
result = fx_api_get_entity_raw(api_url_filter, api_record_start, api_entity),
nextStart = Text.From(Number.From(api_record_start) + api_record_limit),
nextTable = Table.Combine({result, #fxGetEntity(nextStart)}),
check = try nextTable otherwise result
in
check,
resultTable = fxGetEntity("0"),
expandColumn = Table.ExpandRecordColumn(
resultTable,
"Column1",
Record.FieldNames(resultTable{0}[Column1]),
List.Transform(Record.FieldNames(resultTable{0}[Column1]), each _)
)
in
expandColumn
QUESTION TO OP:
Regarding this line:
Result = Source[Result],
Does the json return a field called result instead of data?

Declaring variables in Power Query M Functions

I am trying to create a reusable function in Power Query that will be used by several tables.
This works well (written in blank query):
let
is_emergency = (color as text) =>
if color = "red" or color = "orange" then
"emergency"
else
"not emergency"
in
is_emergency
I can call it using a custom column like this =emergency([color_column]).
However - my color column contains a lot of extra spaces so I somehow need to call Text.Trim() on the color-parameter. How to write this?
What I thought would work was to just write this:
let
is_emergency = (color as text) =>
color = Text.Trim(color, " "),
if color = "red" or color = "orange" then
"emergency"
else
"not emergency"
in
is_emergency
but this gives me the error Token Literal Expected.
How to write it proper? I am aware I can use the Power Query GUI to create simple functions like this, but my real case is more advanced and I would like to understand the M syntax.
I managed to solve it myself after some research.
let
is_emergency = (color as text) =>
// you need to put the variable declaration inside a new let - in
let
trimmed_color = Text.Trim(color, " "),
// you also need to define the return value and return it in the new let - in
return_value = if trimmed_color = "red" or trimmed_color = "orange" then
"emergency"
else
"not emergency"
in
return_value
in
is_emergency

Label displaying "Optional('#') in Swift when using NumberFormatter

I have the following code:
let numberFormatter = NumberFormatter()
numberFormatter.numberStyle = NumberFormatter.Style.decimal
numberFormatter.maximumFractionDigits = 2
let formattedNumber = numberFormatter.string(from: NSNumber(value: rawValue))
currentLogBF.text = "\(formattedNumber) BF"
In the above example, rawValue is a Double that is calculated when all of the input fields have values in them.
currentLogBF is a label in my View.
Whenever a calculation is completed, the label displays something like this:
Optional("12,307.01") BF
How do I get rid of the "Optional()" piece, so it just displays this:
12,307.01 BF
Any ideas what I am doing wrong here?
The function numberFormatter.string(from: NSNumber) will return you a String Optional (String?) instead of String.
You will need to unwrap it first like this
if let formattedNumber = numberFormatter.string(from: NSNumber(value: rawValue)) {
currentLogBF.text = "\(formattedNumber) BF"
} else {
Log.warn("Failed to format number!")
}
And as bonus, use String(format: "%# BF", formattedNumber) rather than "\(formattedNumber) BF" when dealing with optional.
String(format:) will give you compile error when you try to pass optional value as an argument
unwrapping an optional value
let formattedNumber:String? = numberFormatter.string(from: NSNumber(value: rawValue))
currentLogBF.text = "\(formattedNumber!) BF" //optional string. This will result in nil while unwrapping an optional value if value is not initialized or if initialized to nil.
currentLogBF.text = "\(formattedNumber) BF" //Optional("optional string") //nil values are handled in this statement

Add a dynamic key to an anonymous List

How can I add a dynamic key to an anonymous List such as the mydatetime below:
DateTime myDateTime = DateTime.Parse(datepickerval, ukCulture.DateTimeFormat);
var qid = (from p in db.Vw_INTERACTPEOPLE
select p
);
var AvilList = new List<object>();
var ddate = myDateTime.DayOfWeek.ToString().Substring(0, 3) + "Jul" + myDateTime.Day;
foreach (var q in qid)
{
AvilList.Add(
new
{// Availability
Name = q.Fullname,
here >>> ddate = "Some Test"
});
As adam says above there is no way to do this using Lists, however since the Slickgrid is expecting a Json return, I simply built the string in .net then returned it via the JavaScriptSerializer serializer, then in the code behind simply used eval to de-serialize back into an array.
