Open Radar

 
Summary:
The swift compiler fails to compile the code below [this was attached in a project in the original radar]  with "Expression too complex"

public enum SecurityProtocol
{
    case FTP, FTPAccount, HTTP, IRC, NNTP, POP3, SMTP, SOCKS, IMAP, LDAP, AppleTalk, AFP, Telnet, SSH, FTPS, HTTPS, HTTPProxy, HTTPSProxy, FTPProxy, SMB, RTSP, RTSPProxy, DAAP, EPPC, IPP, NNTPS, LDAPS, TelnetS, IMAPS, IRCS, POP3S
    
    let toRawValues = [ FTP: String(kSecAttrProtocolFTP),
        FTPAccount: String(kSecAttrProtocolFTPAccount),
        HTTP: String(kSecAttrProtocolHTTP),
        IRC: String(kSecAttrProtocolIRC),
        NNTP: String(kSecAttrProtocolNNTP),
        POP3: String(kSecAttrProtocolPOP3),
        SMTP: String(kSecAttrProtocolSMTP),
        SOCKS: String(kSecAttrProtocolSOCKS),
        IMAP: String(kSecAttrProtocolIMAP),
        LDAP: String(kSecAttrProtocolLDAP),
        AppleTalk: String(kSecAttrProtocolAppleTalk),
        AFP: String(kSecAttrProtocolAFP),
        Telnet: String(kSecAttrProtocolTelnet),
        SSH: String(kSecAttrProtocolSSH),
        FTPS: String(kSecAttrProtocolFTPS),
        HTTPS: String(kSecAttrProtocolHTTPS),
        HTTPProxy: String(kSecAttrProtocolHTTPProxy),
        HTTPSProxy: String(kSecAttrProtocolHTTPSProxy),
        FTPProxy: String(kSecAttrProtocolFTPProxy),
        SMB: String(kSecAttrProtocolSMB),
        RTSP: String(kSecAttrProtocolRTSP),
        RTSPProxy: String(kSecAttrProtocolRTSPProxy),
        DAAP: String(kSecAttrProtocolDAAP),
        EPPC: String(kSecAttrProtocolEPPC),
        IPP: String(kSecAttrProtocolIPP),
        NNTPS: String(kSecAttrProtocolNNTPS),
        LDAPS: String(kSecAttrProtocolLDAPS),
        TelnetS: String(kSecAttrProtocolTelnetS),
        IMAPS: String(kSecAttrProtocolIMAPS),
        IRCS: String(kSecAttrProtocolIRCS),

}

Steps to Reproduce:
Attempt to compile the attached project in Xcode 6.1 Build 6A1052c or Build 6A1042b

Expected Results:
The file should compile. 31 entries is hardly huge (in fact it will fail with 12).

Actual Results:
The file fails to compile with an expression too complex error.

Version:
