No official money cheats exist for The Sims 3 World Adventures on iOS/iPadOS. The mobile ports (by EA Mobile / Firemint) removed the testingcheatsenabled console and all PC cheat codes.
Third-party "mod menus", "save editors", or "LP generators" for iOS are scams (survey walls, malware, phishing). Jailbreak tweaks exist but violate Apple TOS and risk device instability.
Play the adventure content—it's the core game and pays well.
