Looking for one on one online class on Swift 3 development

Hello all,

for quite some time now, I've been trying to get into Swift development for macOS and iOS.
Unfortunately, however, my journey has been quite unsatisfying to this point. While I'm currently familiar with most parts of the Swift programming language so far, I'm still at the very beginning when it comes to Apple's frameworks, such as Cocoa and Cocoa Touch.
The documentation Apple provides is certainly great, although it can be a bit exhaustive sometimes for the specific case, also there are no exercises or a guided learning path to my knowledge.
Also, as many of you will know certain things are done a bit differently in Xcode when using VoiceOver, such as relying on constraints for designing a user interface or using the Connection Inspecter for creating outlets.
While I am mostly familiar with how these things work, there may still be accessibility-related issues that I might run into, for which it may be necessary for me to talk to someone with more Xcode experience.
So I was thinking that maybe finding someone who can teach me more about app development on a one on one basis would be the most ideal solution, making it possible for me to gain more experience and ask questions when necessary.
Naturally, I would be more than happy to pay for such a service.
So, I was wondering if anybody on here could recommend an institution or single individual who is offering personalized, online Swift classes? My research so far has only revealed on-demand classes which are video based, which probably won't be a great solution.
So, if anybody could recommend a good option, or maybe share their best learning method concerning Swift and Apple's frameworks, I would greatly appreciate that!

All the best,
Robin
