Not sure if its the case for you guys, but apparently after upgrading to 6.4 it asks if you want to load bundles again. I clicked skip without looking and that was blocking alcatraz from showing up in Window -> Package Manager. Long story short run this:

defaults read com.apple.dt.Xcode DVTPlugInManagerNonApplePlugIns-Xcode-6.4

to see if Alcatraz is on the skipped list:

{
    allowed =     {
        "io.realm.RealmPlugin" =         {
            version = 1;
        };
    };
    skipped =     {
        "com.mneorr.Alcatraz" =         {
            version = 1;
        };
        "io.github.FuzzyAutocomplete" =         {
            version = "2.1.0";
        };
    };
}

If it is you can run:
终端输入以下代码即可解决
defaults delete com.apple.dt.Xcode DVTPlugInManagerNonApplePlugIns-Xcode-6.4

and the next time you open xcode it should prompt to load bundles again. Hopefully this helps someone. Original instructions found here
