I am currently working on Material 3. I will have Swift 4.0 in there. It will take a few days to get it going, so until then I will keep this up :)

Thank you very much!

So, according to the Swift Migration Guide https://swift.org/migration-guide/ as long as you compile the cocoapods in Swift 3.2 (not 3.1) you should be able to use them in Swift 4. When I do that though, I still get two compilation errors in the Material library.

One was in Font.swift where font was optional (force-unwrapping here was the quick-fix)

var error: Unmanaged<CFError>?
        if !CTFontManagerRegisterGraphicsFont(font!, &error) {

The other one was in TextStorage.swift where the initializer needed to be marked as required

    /// Initializer.
    public required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

Making these two small changes made the library compile.

I am still confused however because the rest of the pods compiled fine so I am not sure the difference.

Just curious around when Material 3 is scheduled to release?

[danieldahan]

@ssrballin Good question. I am not setting a date, but I am already working on it, making small releases in the 2.* branch.
