So what? When would you EVER as an eladrin wizard use a sword? The only time it MIGHT come up, in theory, would be if you happened to be in a position to do an OA and for some WEIRD reason you actually drew your sword during your turn. You would NEVER EVER attack with the thing, and your OA would be pathetic as well, given an Eladrin Wizard will be lucky to have a 12 STR (maybe 14 at epic, wow). You could totally waste a feat on Intelligent Blademaster, but you still don't have an effective attack that even matches Magic Missile for effectiveness, and you can burn a feat to avoid OAs from using that in melee, and there are a million ways to buff it.
No, in 4e (not that 3e is much better in this way mind you) it requires rather elaborate measures in order to be adequate with both a sword and spellcasting. At the very least you have to pick a fairly obscure class. In 4e Swordmage only appears in the FR player's supplement, Blade Singer is in HotFW, a very late release most people don't have, Hexblade is in HoS, which most people skipped and was also late era, and that about covers it. There WERE good gish options, they were just either very tricky builds requiring specific feats and gear, or very far from being part of the 'core' elements of the game (and still often not the simplest classes to build with).
4e is a great game, but in terms of straightforwardness of builds it is heavily overshadowed by 5e. Pretty much every classic sort of build you would likely see in most 4e games is a single simple choice in 5e, which 'sub-class' you pick at level 2/3 and possibly one or at most 2 feat picks to fully flesh out. Its not a perfect system in that they (IMHO) stupidly stuck 3e-style MCing in there which forced them to ditch the very cool 4e concept of "you are fully your class at level 1" to stop cherry-picking, but that's just a peculiarity of 5e, you could as easily build a system that did it all at level 1 and was still just as straightforward.
Mine did.
That +3 to hit, 1d8 damage gave me a decent OA without having to spend a single resource on it.
Also, it was cool.
Was gonna go Wizard of the Spiral Tower but never made it that high.
