FAQ

Is Kotlin or Swift objectively better?
Neither is universal. The better choice depends on constraints, team skills, compliance, and total cost of ownership.
How often should I revisit this decision?
Markets and product roadmaps move quickly—revisit when pricing, security posture, or your workflow materially changes.
