Since upgrading on Xcode 8 (Beta 1) and Swift 3 I have an error in this line:
account.requestAccessToAccounts(with: accountType, options: nil, completion: {(success: Bool, error: NSError!) -> Void in
It says:
Cannot convert value of type '(Bool, NSError!) -> Void' to expected argument type 'ACAccountStoreRequestAccessCompletionHandler!'
Before that line, I defined "account" and "accountType":
let account = ACAccountStore()
let accountType = account.accountType(
withAccountTypeIdentifier: ACAccountTypeIdentifierTwitter)
This is my (with Xcode 7 and Swift 2 working) code:
func getTimeline() {
//https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=twitterapi&count=2
let account = ACAccountStore()
let accountType = account.accountType(
withAccountTypeIdentifier: ACAccountTypeIdentifierTwitter)
account.requestAccessToAccounts(with: accountType, options: nil,
completion: {(success: Bool, error: NSError!) -> Void in
if success {
let arrayOfAccounts =
account.accounts(with: accountType)
if arrayOfAccounts.count > 0 {
let twitterAccount = arrayOfAccounts.last as! ACAccount
let requestURL = URL(string:
"https://api.twitter.com/1.1/statuses/user_timeline.json")
let parameters = ["screen_name": self.userName!,
"count" : "20"]
let postRequest = SLRequest(forServiceType:
SLServiceTypeTwitter,
requestMethod: SLRequestMethod.GET,
url: requestURL,
parameters: parameters)
postRequest.account = twitterAccount
postRequest.perform(
handler: {(responseData: Data!,
urlResponse: HTTPURLResponse!,
error: NSError!) -> Void in
if error != nil {
Crashlytics.sharedInstance().recordError(error)
}
do {
self.dataSource = try JSONSerialization.jsonObject(with: responseData, options: JSONSerialization.ReadingOptions.mutableLeaves) as! [AnyObject]
if self.dataSource.count != 0 {
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
} catch {
print("catching")
}
})
}
} else {
print("Failed to access account")
}
})
}
error
parameter got changed to an optional instead of an implicitly unwrapped optional. Change it toNSError?
or just remove the explicit types since they are unnecessary anyway. – dan
