初始化时使用Twilio iOS SDK错误

Question

Im tyring to use the Twilio iOS SDK with Swift and when I attempt to initialise a TCDevice Object I get the following error Cannot find an initializer for type 'TCDevice' that accepts an argument list of type '(capabilityToken: NSString?, delegate: nil)'

The code looks like this self.device = TCDevice(capabilityToken: token, delegate: nil)

and the token is this var token = body as? NSString var token = body as? NSString

Any help would be great.

Answer 1

I don't know Twillo, but the only to things I could imagine are these...

Please try this:

self.device = TCDevice(capabilityToken: token!, delegate: self)

To give you the right answer I need the following... please type in your Xcode just this:

self.device = TCDevice(

Than Xcode will autocomplete the initializer... Copy the Autocomplete and post it here... Than I could help you without guessing :-)

Twilio evangelist here.

Pretty sure that the compiler is complaining about you trying to pass it an optional type for the capability token. Try unwrapping the optional:

self.device = TCDevice(capabilityToken: token!, delegate: nil)

Also, check out these two blog posts I wrote on using the Twilio Client for iOS SDK with Swift:

These posts were both written using Swift 1.1, so make sure you also reference the source in Github which has been updated to be compatible with Swift 2. Hope that helps.
