Which way should I follow? .NET or iOS

I am a software engineer working in a FinTech RnD Center in Turkey. I have 2.5 years professional C# and WPF development experience. I also took place in iOS projects. Although I am a .NET guy, I am self-motivated to develop iOS apps in my leisure time. I learn Swift and try to share my know-how with tutorials. I dream, I develop and iterate. I have 2 years experience with Objective C. I developed 5 iOS apps from scratch (3 indie, 2 professional). I like to ship fast and see my product in user hands. I would like to continue my career in Europe (preferably in German or Netherlands). Should I follow .NET path or iOS path for my career through Europe?
