Using isKindOf in Swift

Question

I use Xcode 8.0 beta to test my app, but after it convert my code 2.2 to 3.0, came out many unsolved bugs. Below the demo, Xcode8.0 appear the error message

1. Expected "{" after "if" condition...

    if annotation.isKindof: (MKUserLocation) {
        return nil
    }

Second error is the map kit...I use iskind(of: MKUserLocation) still not work out, it will appear another error message

2.Braced block of statements is an unused closure

    if annotation.isKindof: (MKUserLocation) {
        return nil
    }

3. Missing argument label 'of:' in call

    if annotation.isKind(of: MKUserLocation) {
        return nil
    }

Saddly, it show another error message: 'isKindOfClass' has been renamed to 'isKind(of:)' — Wangdu Lin, Jun 16 '16 at 10:06

The substitute for isKindOf in Swift3 is:

if annotation is MKUserLocation {
    return nil
}
