Hi,
How are you?
I can meet all your criteria.
I am an iOS expert who has 5+ years experiences in iOS app development.
I have high skill at objective-c, swift, cocoa framework and mac os framework.
I also have a graphic designer who has high UI/UX skills for several years.
As you can see in my portfolio, I did a lot of iOS apps before.
Please let us discuss more detail on live chat.
Also I can start to work immediately.
Hope your reply.
Thanks
Gong
