How to call SecItemCopyMatching in Xcode 7 beta 4?

Question

In previous versions of Xcode 6 and 7 with Swift, this syntax would work:

    var secureItemValue: Unmanaged?

    let statusCode: OSStatus = Se         


        

Answer 1

This works on Xcode 7 beta 4

var dataTypeRef: AnyObject?

    let status: OSStatus = withUnsafeMutablePointer(&dataTypeRef) { SecItemCopyMatching(keychainQuery as CFDictionaryRef, UnsafeMutablePointer($0)) }

    if status == noErr {
        return dataTypeRef as? NSData
    }
    else {
        return nil
    }
