What exactly are you forking here? Your README implies that it's for iOS, where every browser is just a skin over Apple's WebKit engine.
(More generally, forking a browser is generally a doomed prospect: even Mozilla and Google struggle to keep up with vulnerabilities and standards churn. Most other forks of Firefox are laughably/irresponsibly stale, and most "forks" of Chrome are really just reskinned Chromium builds.)
Edge represents the best possible case for browser forking: a company approximately the same size as Google, with approximately the same technical resources, and a history of in-house browser development to boot. Most forks are a far cry from that.
