Cannot invoke 'SecPolicyCreateSSL' with an argument list of type '(Bool, String?)' - swift2

HTTPSecurity.swift:124:22: Cannot invoke 'SecPolicyCreateSSL' with an argument list of type '(Bool, String?)'
I'm getting the above error when trying to build a project containing this code:
public func isValid(trust: SecTrustRef, domain: String?) -> Bool {
var tries = 0
while(!self.isReady) {
usleep(1000)
tries += 1
if tries > 5 {
return false //doesn't appear it is going to ever be ready...
}
}
var policy: SecPolicyRef
if self.validatedDN {
policy = SecPolicyCreateSSL(true, domain)
} else {
policy = SecPolicyCreateBasicX509()
}
SecTrustSetPolicies(trust,policy)
if self.usePublicKeys {
if let keys = self.pubKeys {
var trustedCount = 0
let serverPubKeys = publicKeyChainForTrust(trust)
for serverKey in serverPubKeys as [AnyObject] {
for key in keys as [AnyObject] {
if serverKey.isEqual(key) {
trustedCount++
break
}
}
}
if trustedCount == serverPubKeys.count {
return true
}
}
} else if let certs = self.certificates {
let serverCerts = certificateChainForTrust(trust)
var collect = Array<SecCertificate>()
for cert in certs {
if let c = SecCertificateCreateWithData(nil,cert) {
collect.append(c)
}
}
SecTrustSetAnchorCertificates(trust,collect)
var result: SecTrustResultType = 0
SecTrustEvaluate(trust,&result)
let r = Int(result)
if r == kSecTrustResultUnspecified || r == kSecTrustResultProceed {
var trustedCount = 0
for serverCert in serverCerts {
for cert in certs {
if cert == serverCert {
trustedCount++
break
}
}
}
if trustedCount == serverCerts.count {
return true
}
}
}
return false
}

Method using old fashion Boolean which is in fact UInt8. Method also use CFString and not String.
Easy solution is following:
policy = SecPolicyCreateSSL(1, domain as CFString)
More sophisticated solution is use extension for Bool:
extension Bool {
var booleanValue : Boolean {
return self ? 1 : 0
}
init(booleanValue : Boolean) {
self = booleanValue == 0 ? false : true
}
}
Then you can use:
policy = SecPolicyCreateSSL(true.booleanValue, domain as CFString)
