Notarization is more than just signing. It’s an automated security scan by Apple that "staples" a trust ticket to your app. If you distribute outside the Mac App Store, Notarization + Hardened Runtime are your new defaults. Details on Entitlements & Provisioning: blog.xojo.com/2026/03/24/cod… #Xojo #macOS #DevSecurity

What’s your #1 debugging trick? Share your favorite tip, breakpoints, logging, introspection, or something clever? #Xojo #Debugging #Community

Dictionary = key‑value hash. Array = ordered list. Pair = two‑value tuple. true? false? 🤔 #Xojo #Collections #DataStructures

Call REST APIs from Xojo with URLConnection. Send GET/POST async/sync, set headers, handle auth, download files. HTTPS built‑in. 👉 documentation.xojo.com/api/networking… #Xojo #HTTP #API

How do you handle JSON in Xojo? JSONItem vs. manual parsing? Use Compact for network, pretty‑print for logs? Reference: documentation.xojo.com/api/text/json/… #XojoDev #WebAPI

Crash‑proof your Xojo apps with structured exception handling. Catch errors gracefully using Try/Catch, prevent NilObjectException, and keep users happy. 👉 documentation.xojo.com/getting_starte… #Xojo #ErrorHandling #Stability

Just one month until the MBS #Xojo Developer Conference and our Training Day. 15 Countries so far 3 hotel rooms left. You like to join? Marc Zeedar talks about using Apple Foundation Models And Gabriel Ludosanu from Xojo joins the conference. mbsplugins.de/archive/2026-0…

@raximusstudios Great to hear that!

@xojo I just integrated Caddy into my Arcade system to allow deployment of a zip file to hundreds of IoT boards to update them. It works great!

Xojo makes building powerful web apps fast. Now, make deploying them even faster. 🚀 With the Caddy reverse proxy, your Xojo apps get enterprise-grade features out of the box: ✅ Automatic HTTPS for all your Xojo web projects. ✅ Native Load Balancing to scale Xojo instances horizontally. ✅ High Efficiency – save up to 40% on server resources. Focus on building your app’s logic in Xojo and let Caddy handle the infrastructure. See how: blog.xojo.com/2025/08/04/dep… #Xojo #WebDev #Coding #FullStack #SoftwareDevelopment

Nested utility calls make code hard to read. Use Extends to turn ExtractTimestamp(CleanLogEntry(rawLine)) into rawLine.CleanLogEntry.ExtractTimestamp. Cleaner debugging at 2 AM. Guide: blog.xojo.com/2026/03/17/you… #Xojo #ReadableCode

macOS app signing: Which WWDR intermediate certificate do you need? G3, G4, G5 cover most cases. Part 2 breaks down Developer ID Application vs. Installer vs. Apple Distribution certificates and how the private‑key identity works. 👉 blog.xojo.com/2026/03/18/cod… #Xojo #CodeSigning

What kind of applications are you building with Xojo right now? Internal tools, commercial products, utilities, web apps, desktop utilities, mobile apps... Share what you're working on (without revealing secrets, of course). #Xojo #Projects #Showcase

Can Xojo power enterprise‑level applications? Carsten Kobusch's 25‑year ERP project AWARD+ says yes. Read the story: blog.xojo.com/2026/03/11/spo…

Need to talk to another app or computer over the network? TCPSocket is probably what you're looking for, because it can connect, listen, send, and receive data using standard TCP/IP. For secure comms, use SSLSocket. #Xojo #Networking #TCP #Sockets

JSONItem parses and creates JSON strings, essential for API communication, config files, or data storage. Use it as a dictionary (named keys) or array (indexed values). #JSON #API #JSONItem #DataExchange

GraphicsPath creates precise vector shapes for custom UI, icons, or hit‑testing. Build arcs, Bézier curves, rounded rectangles; draw once, reuse anywhere. Key benefits: Mathematical paths (not bitmaps) – scale without quality loss. Hit‑test with Contains() for irregular shapes. Chain MoveToPoint, AddLineToPoint, AddCurveToPoint, etc. #Xojo #Graphics #UI #GraphicsPath #VectorGraphics

Variant: store any data type. Numbers, strings, dates, arrays. Automatic conversion, type detection via .Type. Var v As Variant = "123" Var n As Integer = v // n = 123 #Xojo #DataTypes #FlexibleCode #Variant

Compiler directives give you fine‑grained control over the build process. Use #Pragma to toggle debug‑only code, profile performance hotspots, or conditionally compile for specific platforms (Desktop, Web, Mobile). Do you use any in your projects? #Compiler #Programming #BuildOptimization

Let's be honest: most apps start with "everything in Window1" and stay that way. But at what point does that break down? When do you actually need architecture? What's the tipping point where you regret not structuring earlier? 🤔 #Xojo #DevTalk

Thread synchronization tips: CriticalSection → one resource, one app, recursive-safe Mutex → one resource, OS-wide, named (detect duplicate instances) Semaphore → N resources, counter-based, NOT recursive Pick based on scope and resource count.

Catch specific types: IOException — file/network errors KeyNotFoundException — Dictionary access NilObjectException — null reference OutOfBoundsException — array index errors DatabaseException — SQL failures Multiple Catch blocks for different types. Order matters—specific before general. Finally always executes (unless you Return). Use it for cleanup: close files, release locks, reset state.
