Hello,
I have worked on Google maps SDK for iOS, Can you show me the design you want to implement? Will, there be a popup that appears to edit and flagging icons or you want to edit on top of pin editing option.
BTW I am Jawad, Sr. iOS developer having 4+ years of professional development experience with Swift and Objective-c.
Let me know if you have any questions and when would you like to discuss our next step.
Kind regards,
Jawad Ali
