Getting ambiguous reference to member subscript - swift3

Question

I am updating my code to swift3.0 but getting ambiguous refrence to member? What wrong i might be doing. Here is the method I am getting error in.
open class func parseJsonTenantList(_ list: [NSDictionary]?, strElementName: String, attrName1: String, attrNameValue2: String) -> [TenantRegister]
{
var renantList: [TenantRegister] = []
var key: String?
if let dict : [NSDictionary] = list {
var value: String?
for i in 0..<dict.count {
/// if attribute name doesn't match then it returns nil
if let s1: AnyObject = dict[i].value(forKey: attrName1)
{
key = s1 as? String
}
if let s2: AnyObject = dict[i].value(forKey: attrNameValue2)
{
value = s2 as? String
}
if (!(String.stringIsNilOrEmpty(value) && String.stringIsNilOrEmpty(key)))
{
let t: TenantRegister = TenantRegister()
t.name = key
t.tenantId = Guid(value!)
renantList.append(t)
}
}
}
return renantList
}

The issue is you are using NSDictionary, to solved your problem simply cast the list to Swift's native type [[String:Any]] and then use subscript with it instead of value(forKey:)
if let dict = list as? [[String:Any]] {
var value: String?
for i in 0..<dict.count {
/// if attribute name doesn't match then it returns nil
if let s1 = dict[i][attrName1] as? String
{
key = s1
}
if let s2 = dict[i][attrNameValue2] as? String
{
value = s2
}
if (!(String.stringIsNilOrEmpty(value) && String.stringIsNilOrEmpty(key)))
{
let t: TenantRegister = TenantRegister()
t.name = key
t.tenantId = Guid(value!)
renantList.append(t)
}
}
}
In Swift use native type Dictionary [:] and Array [] instead of NSDictionary and NSArray to overcome this type of issues.
