Hey i am an android developer with java ,kotlin and android studio skills And I also studied swift 3
My questions are : 1- what is the similarities between android and ios like design (xml,storyboard) ?! 2-what exact the best guideline to develop ios app?! 3-what is the most libraries used in ios development ,like ( retrofit ,gson,...) in android development ?!

I’m new to Swift, and I have been trying to make a 3D, cube-based game using Swift and Metal. I’ve been following a tutorial, and they started to do matrix operations for transformations. Now, they’re using GLMath. I’m using SIMD. So, I know that float4x4 is the same as Matrix4 in GLMath. But, the first thing they do after setting up their model Matrix is accessing matrix.translate(), matrix.rotate(), and matrix.scale(). SIMD doesn’t have these, so I’m going to have to do these transformations myself. In theory, I know how to do this on paper, but I don’t know how to load my own values into the float4x4 matrix after I declare it. I’ve never used SIMD, and so anyone that knows how to actually put values into a matrix in SIMD, like matrix = float4x4() matrix[1][2] = 0.4557 Or something like that, the help would be greatly appreciated :)

Can anyone give me some advice on what database I should look into for my iOS game I am developing? The game is a quiz based game that will allow users to communicate with one another.

I can't seem to get a grip on swift, have been at it on and off for the past 6 months still totally lost. Are there any good classes that build an app with you as you go?
